I can't believe how reading all of your horror stories make everything "come together" for me too. I have been on Mirena for almost a month and had side effects from day 3 on. It started with this overwhelming fatigue and what I assume was depression. I am the happiest, most vibrant person and all of the sudden I was fighting back tears for no reason at all. Then around day 5, the cramps started. I thought I was going to die. I couldn't work, couldn't sleep, couldn't play with my kids. It was awful. They subsided after about 4 days. Then the worst happened. I started losing hair...I mean clumps, not just natural shedding. I have long dark hair and when I showered it looked like I was on chemo or something with the amount of hair hitting that shower floor. So scary! Then the headaches, OMG! Awful! Remember, all of this happened to me in just a few weeks time. So I'm freaking out crying last night because of my hair and I call the doctor and they think its my thyroid so they're sending me to an endocrinologist. Then my mom found this website and it all came together for me. MIRENA! So needless to say, I am having it removed tomorrow morning. Oh yeah, and I've gained 7 pounds in 3 weeks...nice.
